Regarding Black Widow, after her recent review she became a beast !! I have her sitting around mid thirties with an AoE build and love her. Check the spoiler for what she can doReed will be 400 splinters.
His tech development time could justify 600 splinters pretty easily, but we are feeling that he is so fun to play that we want more people to try him out and have fun with him.
We're treating his tech as an investment for the future, when we eventually do Stilt Man!
Cosmic Curse - Great use of stealth and massive single target DPS - much fun I like (not mine btw)
